WINDOW-SCREEN.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed June 9, 1905. Serial No. 264,528.

'To all whom, it may concern:

Be it known that I, NATHAN G. ANGLE, a citizen of the United States of America, residing at Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

My invention relates to improvements in removable window-screens; and the invention consists of the particular construction, arrangement, and combination of parts hereinafter fully described, and specifically pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a view in isometrical perspective ofa screen embodying my invention. Fig. 2 is a section at the dotted line 2 2 in Fig. 1 of the same seated and secured in a window-frame. Fig. 3 is an enlarged detail of the locking devices of the screen. Fig. 4 is a section at the dotted line 44 in Fig. 3 of parts there shown. Fig. 5 is a section at the dotted line 5 5 in Fig. i of parts there shown.

Like letters of reference indicate corresponding parts throughout the several views.

A is a rectangular screen-frame formed of upper and lower rails A A and stiles A A, securing them together. The frame is provided with ordinary wire or any desired screencloth A", attached thereto in the usual manner.

B .is a rectangular leaf of the same length as the stiles of the frame and of any desired width, provided with transverse parallel locking-arms B B substantially the same distance apart as and adapted to lap over upon the arms A A and hinged by one side thereof at b to one of such stiles A A*.

C represents buttonholes in the locking arms B B and are provided with correspondingly-slotted face-plates 0, applied and fas.

tened thereover by means of screws D represents long-shanked buttons having -oppositelyinclined cams D D formed thereon to engage the face-plates C of the buttonholes C and rotatably mounted by their shanks D in the baseplates D, which are countersunk into and secured to the rails A A of the screen-frame by means of screws D.

a is the sill of a window-frame provided with sides a, having grooves a 60 therein for the reception of window-sash.

In order to place my improved windowscreen in proper position in a window-frame, the lower sash should be raised a distance equal to the height of the screen,and the lat ter is then inserted into the vertical grooves c in the frame, as indicated by dotted lines in Fig. 2, the screen and its leaf B, when extended and lying in the same plane, equaling thewidth of the window-frame plus the depths of the grooves a therein. The locking-arms B B are secured to the rails A A of the screen frame by inserting the buttons D through the buttonholes Cin such arms B B and turning such buttons to the position shown in Fig. 3, thereby causing the cams D D on the same to closely engage the faceplate (J thereon.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a window-screen, in combination,a screenframe, formed of upper and lower rails A A and stiles A A securing them together and provided with screen-cloth attached thereto, a leaf B provided with transverse parallel locking-arms B B substantially the same distance apart as and adapted to lap over upon the rails A A*, and hinged, at b, to one of such stiles, as A, the locking-arms B B having buttonholes C therein provided with faceplates C applied and fastened thereover, and buttons D having oppositely-inclined cams D D formed thereon to engage the face-plates C of the buttonholes G and rotatably mounted, by their shanks, in base-plates D countersunk into and secured to the rails A A of the screen-frame, substantially as described and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

NATHAN G. ANGLE.
